Our museum is no longer using naphthalene in the entomology store to deter pest insects. We have adopted IPM, but are still grappling with persistent infestations of Anthrenus verbasci. It has been suggested to me that an alternative chemical method should be employed to deter pests, and someone has suggested that we include camphor inside each specimen drawer.
I would like to know if anyone is using camphor in the place of naphthalene, if it is successful at deterring insect pests, (specifically the larvae of Anthrenus verbasci), and any occupational health and safety issues associated with its use. Does camphor crystallise out on specimens and specimen containers like naphthalene? Does it cause any other problems?
Is anyone successfully using any other kind of insect deterrent chemicals with entomology collections?
